Coffee machines and snack vending machines often work with tokens. Tokens are a cheap, easy and comprehensive way to realize control over consumption by customers, visitors or staff.
Many gas stations and other public places with self-service coffee machines do not want cash or bank terminals in their coffee machine, so they centralize the payment via the cash register or a change machine.
Also conference centers, company vending machines,… work with tokens to offer their visitors and staff self-service coffee and snack consumption while controlling the consumption per user.
